Calls Remain Unanswered -

I have been attempting to contact SA Warranties / M-Sure Financial Services throughout the day - with no success. The call is answered with the usual computerised answering system, telling which numbers to press for various departments, and then you just hold on and on , with no human interaction. I have an existing claim that I am trying to sort out through a Policy that I have, and I am also wanting to purchase another Policy - but am finding it extremely difficult to get hold of anybody. How am I supposed to find out what is happening with my claim when I cannot speak to anyone... surely this is unacceptable!
